Do Algonac and Clay Township share any school districts?

Yes — Algonac Community School District. The rate still differs across the municipal line because city millage stacks on top of the school levy, so the same district can cost more in one city than the other.

Will my bill match what the listing shows?

Usually not, in either city. Michigan taxable value uncaps the year after a sale and resets to roughly half the purchase price, so the seller's capped bill on the listing is almost always lower than what you will pay.
